This file was digitised from a VHS recording of the programme. The picture quality is fair, however, the sound track has some occasional static, especially towards the beginning. This episode won an Emmy. It covers the sarcophagus built to contain the remains of the destroyed reactor and the work of the Russian scientists, staff and soldiers who risked and continue to risk their lives in the clean-up operation. I think this is the 1996 updated version of the original 1991 programme and includes an extra 10 minutes of interviews with several of the original scientists. It is shorter than the usual 50 minutes and may have been edited.
